M040300100003 AUTHOR (P.D.Harty,M.N.Thompson,G.J.O'keefe,R.P.Rassool, M040300100004 K.Mori,Y.Fujii,T.Suda,I.Nomura,O.Konno,T.Terasava, M040300100005 Y.Torizuka) M040300100006 REFERENCE (J,PR/C,37,13,1988) M040300100007 INSTITUTE (2JPNTOH) M040300100008 FACILITY (LINAC,2JPNTOH) M040300100009 INC-SOURCE (QMPH,TAGD) M040300100010 SAMPLE The natural-carbon graphite sample was in form of a M040300100011 cylinder, 70 mm in diameter and 100 mm in length. M040300100012 METHOD (TOF,PSD) M040300100013 DETECTOR (SCIN) M040300100014 PART-DET (N) M040300100015 ANALYSIS The absolute differential cross section was obtained M040300100016 with the aid of such quantities as effective number M040300100017 of C-12 nuclei per cm**2, the solid angle of the M040300100018 neutron detector (14.6 msr), the number of tagged M040300100019 photons, the neutron-detection efficiency for each M040300100020 neutron energy, and the neutron-attenuation factor. M040300100021 In order to derive the cross sections to ground and M040300100022 low-lying excited states of C-11, gaussians were M040300100023 fitted to neutron spectra. The gaussians were M040300100024 centered at energies of E-exc = 0, 2.0, 4.6 (average M040300100025 of 4.3 and 4.8), 6.5, and 8.1 MeV, corresponding to M040300100026 low-lying states in C-11. M040300100027 ERR-ANALYS (ERR-S) Statistical errors. M040300100028 (ERR-1) Systematic errors were estimated as 7% due to M040300100029 neutron-detection efficiency, 6% due to neutron M040300100030 scattering correction, and 3% due to tagging M040300100031 efficiency M040300100032 CORRECTION The corrections were made for scattering of neutrons. M040300100033 COMMENT A measurements of the differential photoneutron cross M040300100034 section of C-12 at 65-degrees, between Eg = 30 and M040300100035 100 MeV are reported. Tagged photons, monocromatic M040300100036 to within 2.6 mev, were used, thus allowing the M040300100037 cross sections to a wide range of final states to be M040300100038 observed.
